UITED STATES PATEN `MACHINE FOR ATTACHING MOLDED COUNTER-S T TURNySEIES.

Original application led March 7, 1922, Serial No. 541,667. Dividedandthis application filed September To all whom t may concern.'

Be it known that I, MILTON L. DODGE, a citizen of the United States,residing at Newburyport, in the county of Essex and State ofMassachusetts, have invented new and useful Improvements in Machines forAttaching Molded Counters to Turn Shoes, of which the following is aspecification.

rIhis invention relates `to machines par-` ticularly intended forattaching counter stifener's and shank pieces in position in theuianufacture of turn shoes, and by which this operati-on may be rapidlyand accurately effected, this application being a division of l5applica-tion Serial Number 541,667 filed March 7, 1922, method forattaching molded counters to turn shoes, inwhich the method hereindisclosed is claimed. Heretofore these parts have usually been attachedwhile the last is in the unturned shoe, the shoe `being supported in anailing machineby a jack having in its top a pintor engagement in holein the neck of the last.

, movable forwardly for the placing and removal of shoes and is thenmoved backwardly and raised up into cooperative relation to the'nailingmechanism at each operation. v

' As is well known to those skilled in the ar-t the position of the lastpin hole varies greatly with different lasts and the lasts also varyconsiderably in height.` In 'order to take Careof the variations in theposition of the last pin holes laterally of the last, it has M beenproposed to mount the last pin ina block free to slide laterally' of thejack so that the operator may move it laterally as it `approaches thenailing mechanism to cor-v rectly position it. The proper lateralpositioning of thisblofck, as well'as vertical adjustments for varyinglheights of last requires considerable skill and care on the part of the-operator and slows production very considerably.

is removed before the counter is attached,

and va block, fitting easily within the heel portion of the shoe, isfixed rigidly to the top of the jack. The engagement ot the upper at theheel end of the shoe about this block thus properly centers the shoe sothat it is Valways presented in proper position laterally to' thenailing mechanism, no adjustment being required for different shoes.

ing of the shoe relative to the nailing mechanisms, a centering guidemay be employed against Vwhich the shoe is moved ybeneuith the nailingmechanism.

By this invention, ther of the counter in correct po. lto a mechanicaloperation in wh. ercise of special skill or judgmen sary, so that theoperation v nia.- ifi speeded, the productifniv of impcrtect or im $5erior work eliminated, and a poorer quality of labor may be employedsatisfactorily. thus materially cheapcning the operation. L F or a morecomplete understanding or" .this invention, reference maybe `had to theac- Je companying drawings inwhich f Figure l is a fragmentary sideelevation of the machine showing the relation of the shoesupporting jackto the nailing mechamsm. i i i t Figure 2 is a detail plan ci? the soleand counter gage. A i

Figure 3 is a side elevation ot the shoe supporting block used when woodheels are to be employed, other parts being shown in s0 dotted lines. fV Figure 4 `is a top plan of a block used where wood heels are to beemploy-ed.

'Referring iirstvto Figure l, at l is indicated a jack post which isslidable forwardly e5 and rearwardly in suitable guides on the verticalmovable slide 2.y This machine mav` he of any suitable type of nailingmachine, as

yherein shown it being of the well known lightning type.. The jack l hasat its Q0 outer end an upwardly extending post 3 which, in the ordinaryuse or" the machine for nailing heels, is used to supporty the toe ofthe shoe. At 4is shown an adjustable heel post to 4tho top of which isfixed a block 95 5.. This block inthe present invention isy rigidlyfixed to the top ofthe post 4, centering pins 6 and 7 being shown toinsure its correct positioning and a set screw 8 being employed tofasten the block rigidly in position. At 10 is shown a nailing blockwhich is designedto receive nails in suitable perforations therein andto receive drivn ing members for driving `the nails into a shoesupported on the jack l. rihis block V35 10 is preferably provided onits lateral sides with downwardly extending tingers 1l and on its reartace with a finger 12, These iingers may be yof springy material, ifdesired, so that a molded counter, indicated by 1.1.0

dotted lines at 13, may be pushed upwardly over the block 10, thefingers ll and l2 passing outwardly thereof to retain it in position.Where shank stiieners are to be attached also, these are assembled withthe counters before the latter are positioned for attachment-to theshoes. This nailing block,

together with lingers, is Xed in position on the machine in a well knownmanner. i The jack l may be moved outwardly, away from beneath the block10, into the position shown in dotted lines, to faciiitate the placingof the-shoe thereon,kthis being done when'the slide `2 is depressedbelow cooperative relation with the nailing block. lWhen the jack is inthis position, an unturned shoe, the

last having been removed, is placed over shoe sole is correctly relatedto the path ot movement of the jack so that it will be brought intoproper cooperative relation with the block'lO, and the counter thereon,without particular care on the partei1 the operator.V

The jack is moved rearwardly beneath the nailing block and the sole ofthe shoe engages between outwardly curved spaced." arms 2O (see Figures1 and 2) or a gage 2i.V

This gage 2l is ixed to the upper end of a rod 22V which extends througha guide flange V230 fof a vertically extending track orguide member 23against theV forward race of which the gage slides. The rod 22 extendsdownward c through an opening 2a of a bracket 25 which is fixedcentrally to a top cross member 26 ot a yoke 27 made'fast atopposite-ends by inturned flanges 28 to the top'of the Vslide 2.' Slightvariations in. the

' thickness of the sole are provided for by a spring 30 surrounding therod 22 and bearing in its lower, end against the top face of the bracket25 and at its upper end against a pin 31 extending transversely of therod 22. This vertical movement is for the purpose of correctlypositioning a counter-engaging. gage or centering plate 35, which isalso carried by the rod-22 against the upper face of the gage 21. Thegage 35` has a sloping'inner face 36 which engages beneath the rear endof the counter to properly position it relative to the sole 'in alengthwise Vdirection so that when the `iack l is pushed rearwardly andthe slide 2 raised upwardly, the parts are guided automatically intoproper relative position.V The nailing mechanism is then actuated todrive the nails in `the block 10 through the sole-engaging flange of thecounter in the usual manner to make 1t tast on the upper race of theshoe sole.

- it is sometimes desirable to move the gages 21 and 35 out orcooperative position with the jack and nailing block, as when shoes towhich wood heels are to be applied, are being operated upon. For thispurpose the guide member 23 is Xed to the outer end of a screw i0 whichis slidable through perorations in a pair of spaced `iaws 4l upstandingfrom a bracket 42 which Vis made "fast to a fixed part ot' the machineframe 43'. rThreaded on the screw 40 between the jaws il is a knurlednut d4, by turning which the guide member 23 may be moved tor-V Vwardlyor backwardly relative to the niachine frame and into and out ofcooperative relation with the'jack and nailing block. In order to permitthis motion without binding, the perforation 24 of the bracket V25through which the rod 22 passes is formed daring outwardly toward bothends from an intermediate position to permit ready rocking of the rod 22with reference to the bracket. The position ot` these parts when thegages are out of operative position is shown in dotted lines in VFigure3 in which also a modified construction of jack block particularlyintended for use withV wood heels is shown at 50.

As is well known the outer edge of 'theV heel portion of the shoe'towhich a wood heel is to be attached is beveled loil, 4and betere theshoe is turned'the upper is unattached tothe heel portion ont the sole.When a wood heel is VIto be aiixed therefore, the block rhas a marginalupwardly extending iange portion'l, as shown in Figures 3 and et,withinwhich the sole extendsand against the top of which the edge of thecounter may rest. The block dinayY be of a width sutlicient tosubstantially fit the width of the sole if desired, as shown Vin fulllines in Figure 4, but in order that-a single block may serve forseveral sizes of shoe and therefore recpiireY infrequent change ofblocks for different sizes, they may be made somewhat narrower than theshoe to be operated upon as indicated in dotted lines at 52 (see Figure4t). When such a narrow block is elnployed itis an easy matter for theoperator to center the sole laterally-on the block by placing hisfingers beneath the edge of the sole and in contact with the edge of theblock, the upper, as before stated, being unattached at this point tothe sole and offering no obstruction to this action. The sole andcounter gages are not used at this time, and in order to position thejack correctly rearwardly beneath the nailing block with these gages outof position, an adjustable stop herein shown Vas comprising a Vcap screw55 is kthreaded in a boss 56 projecting vinwardly from the yoke member26. This cap screw may be adjusted and then fixed in position by a locknut 57 thereon so that when the jack 1 is pushed inwardly to impinge onthe head thereof, it is correctly positioned for vertical movement intooperative relation to the nailing block. While as before stated the lastis removed prior to the attachment of the counter and before the shoe isturned, it is usually preferable to turn the toe portion of the shoebefore the counter is attached, this being shown in dotted lines inFigures 1 and 3. When this is done the toe portiony may be supported,when the shoe is initially' placed on the jack, by means of the toe rest3, and when 'the jack is moved upwardly and the sole is engaged betweenthe heel block and the nailing block, the forepart of the shoe is raisedupwardly off the toe rest by the engagement of sole and counter betweenthe blocks 5 andlO substantially as shown. If the forepart of the shoeis not turned prior to the attaching o' the counter, the toe rest islikely to intertere with the downwardly extending uppe v of the shoe.

Having thus described certain embodiments of this invention it should beevident 'to those skilled in the art that many modifications and changesmight be made therein without departing from its spirit or scope asdefined by the appended claims.

I claim:
